LOTOS LT5000D Review: Budget Friendly 50A Air Plasma Cutter

Last Updated on July 4, 2020 by Gary Hargrave

Each plasma cutter comes with some typical features and one or more special highlight(s). You might be committed to plasma cutting on a daily basis or it’s just one of your hobbies. Either way, you’re going to make a choice, and that depends on why and how often you want to use the machine.

High-end and mid-priced models work fine for both hobbyists and professionals, and budget models are good too but only if you’re ready to accept some constraints, such as modest cut capacities, duty cycle, etc. However, those limitations are practically acknowledgeable when it’s a regular and demanding job.

The LT5000D Inverter Plasma Cutter is a popular name among penny wise customers who don’t have any distinguished preference other than regular metal cutting and basic detailing. This LOTOS LT5000D review discusses the key features along with the day-to-day experience you might have with the unit.

The LT5000D is a portable plasma machine offering everything from 50 A power outputs and technical specs to cutting capacities up to 1/2″ and duty cycle rated at 60%; within an acceptable standard considering the price it comes at.

The package includes a 9’9″ 3 prong torch, ground cable and clamp, air regulator and filter, air hose connections (clamps and couplers), air hose, and user manual.

LOTOS LT5000D shares many similarities with a costlier upgrade, LTP5000D which comes with a pilot arc to allow the operator to avoid having the torch in direct contact with the workpiece. It gradually leads to longer consumable life. For a more budget friendly option you can go for the LT3500.

Who Is LOTOS LT5000D for?

People who can’t think of anything besides professional jobs will probably look elsewhere. This unit is kind of cool for the rest of those who need to stay on budget and intend to do simple/basic plasma cutting, especially at home or personal work or repair shops.

Problem You Might Face

Since you won’t have a pilot arc and it doesn’t offer any exclusive function for aluminum which is just one of the several metals it cuts, you’ve got a couple of things to know about.

Using the Torch

Do this in two steps. Get the tip of the torch into direct/proper contact with the edge of the metal being cut. You need a pre-drilled pilot hole for cutting thicker metals in which case, you have to bring the tip in contact with that hole. Now, you can start the job by press the designated button.

Once you’ve started cutting; it’s time to ensure that the copper tip and the metal being cut aren’t into a direct contact. Keep the torch inclined and maintain a gap of 1 mm in between the copper tip and the metal. It’ll help you protect that tip from quick damages.

Cutting Aluminum and Rusty Metal

Regardless of what the manufacturer says about the unit’s ability to cut aluminum, you shouldn’t choose anything thicker than 1/4 inch in general and 3/8 inch in particular (where slow speed doesn’t hurt).

While cutting rusty metal, spend a few moments to clean the surface first because the existing one wouldn’t be helpful as you hope to have clean and smooth cuts.

Pros

  • A purpose-built plasma cutter for budget-conscious buyers
  • Inverter technology for lightweight design yet improved functions and digital read-out for saving guesswork
  • MOSFET transistors for increased current output for cutting thick and hard material
  • Excellent duty cycle for allowing extended plasma cutting sessions
  • Pulse-Width-Modulation (PWM) for an efficient control of the current flow through the motor
  • PAPST Cooling System for cooling the unit quickly and safely

Cons

  • Presumably brief lifespan (Not a suitable choice for those who don’t want something for a short-term support)

LOTOS LT5000D review: Features and Benefits

LOTOS plasma cutters aren’t usually left without some smart innovations. LT5000D isn’t an exception. The following discussion focuses on each feature and component that contributed to its being so well-liked.

Cut Capacities and Performance

Preferred metals for plasma cutting include steel, aluminum, copper, alloy, and other metals. For this unit, best results come with steel and aluminum.

  • For 10-gauge mild steel, cut thickness can be 1/4″, 3/8″ (recommended), 1/2″, and 5/8″ (maximum)
  • For 10-gauge stainless steel, it can be 1/4″, 3/8″ (recommended), and 1/2″ (maximum)
  • For aluminum, thickness can be 1/8″, 1/4″ (recommended), 3/8″, and 1/2″ (maximum)

Special Technologies and Components

LT5000D comes as a result of the popular inverter technology being combined with MOSFET transistors for a lightweight transformer which results in improved operational efficiency.

Pulse-Width Modulation helps keep the amplitude of the voltage constant to ensure that the motor remains at its full strength all the time. Dual Voltage enables the machine to use 220 V 50/60 Hz or 110 V 50/60 Hz directly in connection with a pigtail that doesn’t come included.

Duty Cycle and Power Output

Rated duty cycle is 60% at 50 amps using both 110V and 220V, and the current output ranges from 10 amps to 50 amps. So, you can get 6 minutes of continuous cutting before leaving the unit for cooling for 4 minutes.

Other Features

Some of the features may not seem very special to you, but they’ll improve your experience during day-to-day works. The Digital read-out system displays precise information leaving no need for assuming any approximate number.

There’s a ‘Problem Indicator LED’ which does exactly as its name suggests. It lets you know when to shut off the system and check on its components for potential problems. You can adjust the cutting current to suit to the specific demands of the task at hand.

The unit has an internal cooling system that works when the machine gets heated due to an exhausted duty cycle.

Final Words

What’s your key consideration about LOTOS 50A Inverter Plasma Cutter – just a plasma cutter for beginners or a reliable metalworking tool for occasional uses?

One way or another, both ideas are appropriate and specific to your individual expectations. You can’t have it running like a souped-up machine. But, its usability can be as good as a budget-friendly model gets.

Its cut thickness and speed can’t be as impressive as those of a sophisticated model, but they’re still admissible for users who needn’t put their units into action more than once or twice a week. Hopefully, you can make a move now.
